The current trends in use of mitra clip in the US between 2010-2014.

Background
The Mitraclip is a new, minimally invasive procedure for severe mitral regurgitation. This study was performed to recognize demographic features and analyze the current trends in use of the Mitraclip clip in the US between 2010-2014 utilizing the NIS database.

Methods
Nationwide Inpatient Sample (NIS) data was used to extract data of patients undergoing Mitraclip procedure during index admission for years 2010-2014. Patients were identified by ICD-9 procedure code 35.97 which represents percutaneous mitral valve repair with implant. Demographic features and trends in the use of Mitraclip over the five year period were analyzed.

Results
A total of 2948 indexed procedures of percutaneous mitral valve repair were performed in between 2010 and 2014. Of all patients 59% were males and 41% were females. There was continuous upward trend with the largest increase (3 fold) in number of procedures between 2013 and 2014.The Mitraclip was used most often in patients aged 65-84 year-old (51.6%). The main insurance was Medicare paying for 75% of all procedures. Vast majority of implantations were performed in urban hospitals (95.61%), predominantly in teaching institutions (56.9%).

Conclusions
Our data was showing upward trend in Mitraclip implantation between 2011 and 2014. it is anticipated that this trend will continue. The results of recently presented COAPT trial may contribute to the expansion of Mitraclip procedure in the US.
